Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542420, here are decompositions:

13 + 33542407 = 33542420
19 + 33542401 = 33542420
31 + 33542389 = 33542420
61 + 33542359 = 33542420
97 + 33542323 = 33542420
157 + 33542263 = 33542420
193 + 33542227 = 33542420
229 + 33542191 = 33542420

Showing the first eight; more decompositions exist.
